Starter-interrupt device incorporating global positioning system functionality

ABSTRACT

An onboard starter-interrupt device incorporates Global Positioning System (GPS) functionality in addition to payment schedule enforcement functions. In response to certain events, and/or on a periodic basis, the onboard device transmits vehicle location data to an operations center. In one aspect, a “geo-fence”, or virtual boundary, can be defined; if the vehicle is driven outside the geo-fence, the location information is transmitted to the operations center and/or other action is taken. In response to receiving vehicle location data, the operations center can send a message to cause the onboard device to disable the vehicle, or to present a warning to the vehicle owner, or to notify a third party of the event and/or vehicle location, or any combination thereof.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 11/539,292 filed Oct. 6, 2006 titled “Starter-Interrupt Device Incorporating Global Positioning System Functionality”, which was a continuation-in-part of U.S. patent application Ser. No. 11/349,523 filed Feb. 7, 2006 and titled “Enforcing Payment Schedules”. The listed applications are incorporated by reference herein as if reproduced in full below.

FIELD OF THE INVENTION

The various embodiments described herein relate to the use of Global Positioning System (GPS) functionality in the context of a payment enforcement system that disables, alerts, and locates a vehicle in response to a missed payment or other event.

DESCRIPTION OF RELATED ART

Lenders have various mechanisms for enforcing payment of debt obligations, particularly those obligations that arise from the sale of goods or property on credit. For example, mortgagees can foreclose on real property if a mortgagor defaults. Vehicle finance companies can repossess a vehicle in the event the owner fails to make timely payment.

In some cases, foreclosure payment schedule enforcement mechanisms are expensive and/or cumbersome to implement. Accordingly, lenders often refuse to extend credit when the likelihood of default exceeds some amount, because of the expense or impracticality of repossessing or otherwise enforcing payment obligations. In particular, potential buyers with poor credit history may be denied credit when attempting to purchase a vehicle or other item because of the relatively high likelihood of default. In addition, payments on less expensive items such as appliances, computers, and the like are often difficult to enforce because repossession is far too expensive in relation to the value of the item itself, and because the item loses much of its value once it is used.

Payment enforcement systems exist whereby a vehicle (or other purchased property) is equipped with a device capable of disabling the vehicle in the event of non-payment. Whenever the purchaser/owner makes a timely payment, he or she is given a password to enter on a keypad installed in the vehicle. Entry of the password enables the vehicle for some limited period of time (usually until the next payment due date, plus some grace period). Failure to enter the password causes the vehicle to be disabled, for example by interrupting the starter circuitry. Usually, the owner is given some warning of impending disablement, and may also be provided with a limited number of emergency starts whereby the vehicle can be used a few times even if a code has not been entered. In some variations, the password is transmitted wirelessly to the vehicle so that the owner need not enter it manually.

Such systems, available for example from PassTime USA of Littleton, Colo., are effective in reducing the incidence of delinquency and default. However, a significant level of default remains, which the lender is forced to engage in costly repossession activities.

In addition, lenders often want to know where the vehicle is, particularly in cases of default. Such information would be useful in reducing the cost of repossession. Furthermore, providing such information to lenders can reduce the likelihood of default, particularly if the owner of the vehicle is informed of the fact that location information is being made available to lenders.

It may also be useful to provide lenders (and/or others) with location information in response to certain trigger events, such as detecting that a vehicle is being taken out of state or out of country.

What is needed, therefore, is a device that is able to disable a vehicle in response to certain events such as non-payment, and also provides location tracking information to lenders (and/or others) in response to certain events. What is further needed is a device that performs such functions without unduly impinging on customer privacy. What is further needed is a device that performs such functions without imposing undue burden or effort on the vehicle owner.

SUMMARY

Various embodiments combine remote vehicle disablement with location tracking information, so as to provide a payment assurance solution that reduces the risk of default and also reduces the cost of repossession in the event of default. The various embodiments may perform such functions in a manner that respects the privacy of the vehicle owner, and that imposes little or no burden on the owner.

According to the techniques described herein, an improved onboard starter-interrupt device incorporates Global Positioning System (GPS) functionality in addition to payment schedule enforcement functions. In response to certain events, and/or on a periodic basis, the onboard device transmits vehicle location data to an operations center. These events can include, for example, a request from the operations center, detection of unauthorized use, dismantling, or tampering of the vehicle or the onboard device, driving the vehicle outside permissible boundaries, and the like. In one aspect, a “geo-fence”, or virtual boundary, can be defined; if the vehicle is driven outside the geo-fence, the location information is transmitted to the operations center and/or other action is taken.

In response to receiving vehicle location data, the operations center can send a message to cause the onboard device to disable the vehicle, or to present a warning to the vehicle owner, or to notify a third party of the event and/or vehicle location, or any combination thereof. Alternatively, the operations center can alert an operator as to the event and/or location of the vehicle, and await further instructions from the operator.

In one aspect, detection of certain location information at the vehicle can cause the onboard device to immediately disable the vehicle before instructions are received from the operations center. The device can then await further instructions from the operations center. In this manner, a “fail-safe” provision can be implemented that disables the vehicle in the event certain location information is detected and no communication can be established with the operations center.

In one aspect, a payment schedule can be configured. If the vehicle owner fails to make payment by a certain date, the operations center can send a message to the onboard device to output alerts, disable the vehicle, provide location information, or any combination thereof in any desired sequence.

By combining vehicle disablement technology with location detection, various embodiment may provide an improved system and method for enforcing payment schedules and reducing the likelihood and cost of default.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Enforcement of payment schedules in a centralized, flexible manner is described in related co-pending U.S. patent application Ser. No. 11/349,523 for “ENFORCING PAYMENT SCHEDULES”, filed Feb. 7, 2006, the disclosure of which is incorporated herein by reference. As described therein, various types of events can be configured via software running at an operations center. Upon occurrence of a specified event, a message is sent to a remotely located device, such as one installed in a vehicle or other product. The onboard device is configured so that it can disable the vehicle (for example by disabling the starter circuitry) upon receipt of the message from the operations center. In implementations involving products other than vehicles, other mechanisms for disabling the product (such as cutting off power to the product) can be used. The remotely located device can be instructed to allow a certain number of emergency uses, or to accept an override password that re-enables use of the vehicle.

In one embodiment, location tracking functionality is implemented in connection with the onboard device. The location tracking functionality is implemented, for example, using known global positioning system (GPS) technology. The onboard device can be programmed to periodically transmit location information to a central operations center, and/or to transmit such information in response to particular events, and/or to automatically output warnings/alerts to the vehicle operator in response to particular events, and/or to automatically disable the vehicle in response to particular events. Software at the operations center allows a system administrator to configure the system and to specify which events cause which actions to be taken. In addition, certain events (such as nonpayment) can be detected at the operations center, causing a message to be sent to the onboard device and result in disabling or affecting the operation of the vehicle, warnings, location reporting, or any combination thereof.

For illustrative purposes, the description provided herein sets forth the example embodiments in the context of vehicles and vehicle location tracking. However, one skilled in the art will recognize that the various embodiments can be used in connection with any product, particularly products that are capable of being moved from one location to another. For example, locations of consumer electronic devices, wide-screen televisions, appliances, and the like can be reported according to the techniques set forth herein.

According to one embodiment, the method/system is implemented as a software application running at an operations center. The software application receives location information from a GPS tracking mechanism, detects relevant events such as nonpayment and geo-fence violations, and generates messages in response to the events. These messages are received by remotely located devices installed in vehicles or other products. Upon receiving a message, the remotely located device takes appropriate action, disabling the vehicle, transmitting its current location, outputting alerts, or the like.

Referring now to FIG. 1, there is shown a block diagram depicting an overall architecture for an embodiment. Software 102 running at operations center 101 performs much of the functionality. In one embodiment, operations center 101 is situated at some central location and is operated by or on behalf of a lender, seller, or loan service company. Appropriate communications infrastructure, such as Internet, wireless, and/or telecommunications connectivity is provided, so as to allow operations center 101 to communicate with other elements of the overall system.

Onboard device 111 is located in vehicle 109 and includes a processor, such as PIC processor 1105, which implements the onboard functionality. PIC processor 1105 interfaces with wireless modem 120 for sending and receiving messages, output device 113 for presenting output to owner 110, and GPS module 114 for determining vehicle location. Software running on PIC processor 1105 controls enablement and disablement of vehicle starter circuitry 112. In one embodiment, PIC processor 1105 is communicatively coupled to vehicle starter circuitry 112 to facilitate such disablement when needed. In other embodiments, PIC processor 1105 is coupled to other vehicle circuitry such as a Controller Area Network (CAN) bus, on-board diagnostic (OBD) port, or the like, so that it can affect operation of vehicle 109 by disabling, curtailing, or limiting certain features and functions of vehicle 109 as appropriate. For example, under certain conditions, vehicle speed and/or vehicle functionality may be limited in response to a nonpayment event.

System administrator 104 interacts with software 102 via user interface 103, which allows system administrator 104 to specify options, schedules, alert conditions, and the like, and also allows system administrator 104 to view reports, monitor system operations, and the like. System administrator 104 may be located at or near operations center 101, or may be remotely located, in which case interactions with software 102 may take place over a computer network such as the Internet, virtual private network, or the like, according to techniques that are well known to those of skill in the art.

Technology trigger 121 provides messages 107C specifying events that have occurred. Technology trigger 121 can be any source of information that is relevant to the payment schedule enforcement mechanism. For example, technology trigger 121 may be a data stream providing information from a payment system, so that upon receipt of messages 107C from technology trigger 121, software causes payment schedule 105 and/or other information to be updated.

Event logic 115 specifies what actions should be taken in response to such messages 107C. For example, technology trigger 121 can inform software 102 that a payment has been received, or that a payment has been missed, or that some other event has taken place. Event logic 115 tells software 102 what to do in response to such events.

Payment schedule 105 for a particular debtor is stored, for example, in a database or other data store at operations center 101 or at some other location. Software 102 enforces payment schedule 105 by sending appropriate messages according to event logic 115, on-demand needs, or local override. Software 102 uses mapping information 116 to detect geo-fence violations and to otherwise interpret vehicle location information received from onboard device 111. Software 102 is communicatively coupled with accounting systems (not shown) or other sources of data that inform software 102 when a payment is late or when other relevant events take place that require messages 107A, 107B to be sent.

In one embodiment, software 102 also includes data management module 117, which maintains customer information, financial controls, verification data to ensure authenticity of messages 107A from vehicles 109, and the like. Such information can be stored in database 118, which in one embodiment is implemented as a SQL server database. Data management module 117 can also maintain payment schedules 105, and can specify changes to event logic 115, under the control of user interface 103.

In one embodiment, software 102 invokes middleware 106 to send messages 107A, via wireless carrier 119, to modem 120 associated with device 111 at vehicle 109. In one embodiment, middleware 106 can also be used for sending messages 107B to external agent 108, although in other embodiments messages 107B are sent directly by software 102. For example, middleware 106 can communicate with a cellular network via Internet Protocol; messages are then sent via the cellular network using a GSM or other protocol to modem 120 in vehicle 109. External agent 108 can receive information regarding vehicle 109 by other means, for example by receiving email messages from operations center 101, or by logging onto a web site run by operations center 101.

In one embodiment, messages are sent using an Access Point Name (APN) associated with a wireless carrier 119 communicating via a GPRS protocol. Any other network or protocol can be used, including for example GSM, CMDA, or the like. The APN enables sending and/or receiving messages to external agent 108 and/or wireless modem 120 on onboard device 111. Middleware 106 provides an interface by which software 102 can communicate with many different types of devices, systems, computers, vehicles, nodes, and the like, via a variety of protocols, to provide mobile device control and data acquisition functionality. Essentially, middleware 106 acts a protocol translation module between software 102 and whatever entities software 102 communicates with. For example, for certain devices 111, Internet Protocol (IP) may be an appropriate communication medium, whereas cell or pager messages may be the appropriate mechanism for other devices 111. Examples of other communication protocols that can be used include GPRS, SMS Edge, Java, SQL and the like. In one embodiment, the method/system is implemented using mobile device middleware available from Intellimatics of Coppell, Tex. Standard ODBC protocols can be used to communicate with Intellimatics databases (via standard SQL commands, a SQL Server database, and UDP, SMS, and/or TCP/IP messaging protocols).

Event management middleware 106 sends messages 107A to remotely located device 111 installed in vehicle 109. In one embodiment, modem 120 in device 111 receives such messages 107A. Messages 107A instruct device 111 to perform various operations, such as disabling vehicle starter circuitry 112 in order to prevent operation of vehicle 109, outputting alerts or other information to owner 110 via output mechanism 113, reporting location information, or the like. Output mechanism 113 may be a speaker for issuing beeps and spoken information, or it may be a display screen for showing visual alerts, SMS alerts, email messages, text alerts, or some combination thereof. In one embodiment, output mechanism 113 is a standalone output device that is connected to or part of device 111; in another embodiment, output mechanism 113 can be implemented as part of an existing component of vehicle 109 such as a GPS navigation system, onboard trip computer, or other component. In this manner, the techniques of the vrious embodiments can be implemented in a manner that is well integrated with existing input and output mechanisms already present in vehicle 109.

In addition to sending messages 107A and/or 107B, in one embodiment, middleware 106 can also receive messages. For example, middleware 106 may receive acknowledgement messages from device 111 and/or agent 108 to confirm receipt of messages 107A and/or 107B. Middleware 106 also receives vehicle location data from GPS module 114 located at vehicle 109. GPS module 114 can be any device or circuitry for detecting vehicle location, and may be implemented as a component of onboard device 111 or as a separate component capable of communicating with operations center 101. GPS module 114 can use existing GPS functionality in vehicle 109 (such as may be found in the navigation system of vehicle 109), or it can use separate GPS functionality. In an alternative embodiment, middleware 106 can be omitted, and software 102 communicates directly with device 111 via wireless carrier 119 to exchange such information.

In one embodiment, middleware 106 receives data from GPS module 114 which is part of onboard device 111. In another embodiment, operations center 101 receives such data from GPS module 114 or device 111 directly, without using middleware 106.

Although the various embodiments are described in connection with an embodiment using middleware 106, one skilled in the art will recognize that other embodiments are possible. In particular, middleware 106 can be omitted, so that software 102 communicates directly with onboard device 111 and/or external agent 108, as appropriate.

In one embodiment, GPS module 114 provides location information periodically (such as every minute, or every hour). Onboard device 111 records such information locally, and transmits the information to operations center 101 in response to some trigger event.

For example, onboard device 111 can be configured to report vehicle location data to operations center 101 in response to any of the following:

periodically (for example, once every hour or once every day);

upon detecting that vehicle 109 is being driven outside defined bounds (referred to herein as a “geo-fence”);

upon detecting that vehicle 109 is being driven across state lines or across an international border;

upon detecting that vehicle 109 and/or onboard device 111 and/or GPS module 114 is being modified, tampered with, dismantled, circumvented, disabled, or the like, or that any attempt has been made to do so;

upon receiving a message from operations center 101 instructing onboard device 111 to report vehicle location.

When onboard device 111 reports vehicle location data to operations center 101, it can report current location. Also, if appropriate, it can report a series of locations that have been visited since the last report. In one embodiment, the information describing the series of locations is stored locally at device 111 until it is transmitted to operations center 101, at which time it may be purged from device 111 or archived.

One skilled in the art will recognize that many other trigger events can be specified. In connection with any of the above (or other) trigger events, onboard device 111 can cause vehicle 109 to be disabled, and/or a warning or alert can be output via output device 113 to vehicle owner 110, and/or a message can be sent to operations center 101 and/or to external agent 108.

In various situations, other information may also transmitted to operations center 101, either via middleware 106 or directly. For example, it may be useful to provide mileage information, such as to enforce mileage limits on rented or leased vehicles, or to determine whether preventative maintenance schedules are being followed.

Referring now to FIG. 2, there is shown a flowchart depicting an example of a method of practicing the various embodiments, where a geo-fence violation causes vehicle 109 to be disabled.

A geo-fence is specified 701, indicating where the vehicle 109 may be driven. For example, the terms of the purchase/lease agreement may impose territorial limitations on where the vehicle can be taken (within a state, within a country, within a certain radius of a defined point, or the like). In one embodiment, system administrator 104 specifies geo-fence using graphical tools provided by user interface 103. For example, system administrator 104 can draw a perimeter on an on-screen map; mapping module 116 interprets the drawn perimeter to define the parameters of the geo-fence.

In addition, certain “danger areas” can be specified as being off-limits (for example scrap yards, impound lots, car auction sites, or other locations associated with unauthorized activity in connection with used vehicles. Specifying such danger areas provides a mechanism by which operations center 101 can be kept proactively informed as to the whereabouts of vehicle 109, in particular when there is a possibility that the vehicle may be sold or otherwise disposed of in an unauthorized fashion.

Administrator 104 can provide geo-fence and/or danger area information via UI 103, and such information is stored at operations center 101 for use by event logic 115. As vehicle 109 is being driven, GPS module 114 continually monitors 702 vehicle 109 location. As mentioned above, GPS module 114 can be part of the vehicle's 109 navigation system, or a separate component. On-board device 111 receives location information from GPS module 114 and periodically sends such information to operations center 101.

A violation is detected 703 based on information provided by GPS module 114. In one embodiment, operations center 101 provides onboard device 111 with geo-fence information, so that device 111 can immediately detect 702 a geo-fence violation upon receipt of certain location information from GPS module 114. Device 111 then informs operations center 101 of the violation. Operations center 101 sends a message 107A to device 111 telling it what to do, such as for example: disable the vehicle 704; output a warning to owner 110; output a warning and then (after some period of time) disable the vehicle 704; or the like. Operations center 101 can also send a message 107B to external agent 108 such as a repossession agent; message 107B can include location information to facilitate repossession of vehicle 109. In one embodiment, device 111 can be programmed to immediately disable vehicle 109 upon detecting 703 a geo-fence violation and to await further instructions from operations center 101. In such a manner, a “fail-safe” mechanism is implemented that allows for the possibility that no communication with operations center 101 can be established. Furthermore, in the event of lost communication, operations center 101 can immediately alert an external agent 108 to dispatch a repossession agent or other individual to the last known location of vehicle 109.

In another embodiment, geo-fence violations are detected 703 at operations center 101 rather than at vehicle 109. Geo-fence information is maintained at operations center 101. Device 111 informs operations center 101 of the location of vehicle 109. Operations center 101 detects 703 geo-fence violations by comparing current location with geo-fence information. When a violation is detected, operations center 101 sends a message 107A to device 111 telling it what to do, such as for example: disable the vehicle 704; output a warning to owner 110; output a warning and then (after some period of time) disable the vehicle 704; or the like. As described above, operations center 101 can also send a message 107B to external agent 108 such as a repossession agent; message 107B can include location information to facilitate repossession of vehicle 109.

By notifying operations center 101 when vehicle 109 re-enters the defined geographic region, the various embodiments provide a mechanism by which a repossession agent can be notified that the sought-after customer is now back in its home state. In some cases, this might reduce the repossession rate charged by the repossession agent.

The above-described example depicts an embodiment where a geo-fence is imposed at all times. Alternatively, a geo-fence can be imposed in response to a nonpayment event. Referring now to FIG. 8, there is shown a flowchart depicting an example of such a method. Technology trigger 121 detects 801 a nonpayment event. This event can be detected 801, for example, by consulting a payment schedule 105 previously received and stored at operations center 101. The operations by which software 102 receives payment schedule 105 may take place under the control of system administrator 104 via user interface 103. In addition, administrator 104 can specify, via user interface 103, the characteristics of payment schedule 105 and the various actions that should be taken in response to various conditions.

Technology trigger 121 informs software 102 at operations center 101 that a nonpayment event has occurred. Event logic 115 specifies that in response to a nonpayment event, a geo-fence should be imposed and an alert (warning) should be presented to vehicle owner 110. Accordingly, software 102 transmits 802 a message 107A to onboard device 111 containing terms of the geo-fence and grace period (if applicable), and indicating that an alert should be presented. The geo-fence terms can contain a perimeter beyond which the vehicle 109 is not allowed to travel. This perimeter can be defined by latitude/longitude coordinates, or by distance from a known location, or by any other means.

Output mechanism 113 at vehicle 109 outputs 803 the alert, informing vehicle owner 110 that a nonpayment event or other contract violation has occurred. The alert can also inform owner 110 of the grace period for payment, if applicable. Device 111 can be configured/instructed to provide additional alerts via output mechanism 113 as the expiration of the grace period approaches.

Device 111 imposes the geo-fence 804. GPS module 114 informs device 111 of current vehicle locations at regular intervals (for example once a minute). If, according to location information provided by GPS module 114, device 111 detects 805 a violation of the geo-fence, a message 107A is sent 808 to notify operations center 101 of the geo-fence violation. Optionally, vehicle can be disabled (or its operation can be affected or curtailed) upon detection of a geo-fence violation, although in one embodiment such action takes place upon receiving a disable command from operations center 101. System administrator 104 can be automatically notified by email, pager, SMS/text message, or the like. If appropriate, a message 107B can be sent (either by operations center 101, or directly from device 111, or from system administrator 104) to external agent 108. External agent 108 can be, for example, a repossession agent that will dispatch a tow truck to claim the vehicle. Message 107B to external agent 108 contains location information for vehicle 109 so that vehicle 109 can be easily found. In certain situations, other entities can be notified, such as a credit card company, lender, and/or a roadside assistance provider.

If the grace period expires 807 without payment being received, similar action can be taken: operations center 101 is notified 808, vehicle 109 may (optionally) be disabled 806 or its operation may be affected or curtailed, and (optionally) external agent 108 is provided with location information to claim the vehicle.

If payment is received 809, the geo-fence and/or the vehicle disable command are lifted 810. A message can be provided, via output mechanism 113, to inform owner 110 that the geo-fence and/or the vehicle disable command have been lifted.

Even when the strict geo-fence imposed in step 804 is not in effect, in some embodiments location information is still periodically transmitted to operations center 101. Certain events, such as traveling outside the country or across state lines, tampering with the system, and/or the like, can cause a similar sequence of steps to be taken as depicted in FIG. 8.

For example, owner 110 can be alerted to a violation of purchase/lease terms and can be given a warning to immediately return to the permitted geographical region. Failure to return can cause vehicle disablement and can cause a message (including location information) to be sent to external agent 108 to repossess the vehicle.

As indicated above, the example systems can be used with products other than vehicles as well, in which case device 111 might be located in or attached to whatever product is subject to being remotely disabled according to the methods provided herein. In such embodiments, device 111 is configured and situated so that it is capable of disabling the subject product when it receives a message instructing it to do so. For example, device 111 can be configured to be able to shut off a power source (such as 110-volt AC) to an appliance or other product.

In one embodiment, device 111 receives communications from middleware 106 via the same physical medium as is used to power the product (such as AC power lines). Such an arrangement prevents owner 110 (or some other individual) from disabling communications with middleware 106 without also cutting off power to the product. Such an embodiment may be effective for payment enforcement on appliances that run on AC power.

Device 111 can include additional components to enhance functionality. In one embodiment, device 111 includes a WiFi repeater to enable communication with vehicle 109 or other products. The repeater is capable of enabling and/or disabling certain actions within the vehicle such as fuel, ignition, or other components. Device 111 can communicate with middleware 106 using any wireless or wired communication channel, including for example Internet, cellular, radio, GSM, pager, or the like. In one embodiment, device 111 periodically polls middleware 106 for messages; alternatively, device 111 is passive and only responds when middleware 106 sends messages. In one embodiment, device 111 has an IP address so that it can be directly addressed via the Internet protocol.

Messages 107A and 107B may be encoded using any known encoding scheme or protocol. In one embodiment, messages 107A and 107B are password-protected and/or encrypted to reduce the possibility of interception and/or tampering.

Hardware Architecture

Referring now to FIG. 11, there is shown an example of a hardware architecture for onboard device 111 according to one embodiment.

Wireless communication module 1104 enables communication with operations center 101 by known mechanisms such as GPRS. In one embodiment, wireless communication module 1104 is a Wavecom Q26 processing module including a processor and functioning as a quad band GSM/GPRS package. It contains two universal asynchronous receiver transmitters (UARTs), labeled UART1 1106 and UART2 1107, for communication with other components. It also contains a Serial Peripheral Interface Bus (SPI) 1108 for communication with CAN interface and a General Purpose Input/Output (GPIO) 1109 for communication with virtual module 1105. Module 1104 is connected to modem 120 for enabling wireless communication with operations center 101.

In one embodiment, modem 120 implements quad-band GSM/GPRS/CDMA or other protocol(s) according to known techniques. In one embodiment, device 111 includes an SMA connector for GSM antenna. A provisioning interface uses an established web service for provisioning and administration of SIM cards embedded in modem 120.

Virtual module 1105 contains circuitry for performing functionality described herein. In one embodiment, virtual module 1105 is implemented as a PICmicro microcontroller available from Microchip Technology of Chandler, Ariz. In one embodiment, infrared port 1110 is a serial port that communicates with GPIO 1109 of module 1104. Starter interrupt 1111 connects with vehicle starter circuitry 112 to selectively disable vehicle 109 when appropriate.

In one embodiment, applications 1201 and 1210 operate according to instructions received from operations center 101, which transmits commands and other information to device 111 via wireless communication techniques as described above.

Software Operation

User interface 103 provides a mechanism by which system administrators 104 can issue commands, track vehicles, review payment history, and the like. UI 103 interacts with software 102, which retrieves relevant data from database 118 and interacts with middleware 106 to send commands to device 111. In one embodiment, commands to be sent via wireless carrier 119 are inserted in database 118. Middleware 106 scans database 118 for new updates. Once an update is found, the new data is encapsulated in a UDP packet and sent via carrier 119. The message is sent via GPRS to vehicle 109 and/or to external agent 108 as appropriate.

Modems in vehicles 109 can be configured for automatic position reporting. For example, they can be configured to send GPS position, vector and satellite information at one-minute intervals. Operations center 101 receives this information and stores it in database 118. Operations center 101 parses the information into the appropriate GPS tables in database 118 (position, vector, and satellite). Mapping module 116 is used to interpret the GPS data. Information is also stored in database 118 for GPS history (such as scheduled interval reporting, or breadcrumbs), Geo-fencing and reverse geo-coding.

The following table 1 summarizes commands that can be handled by device 111 according to one embodiment:
